Agent for Escherichia coli INTRODUCTION a. Background of the Study We all know that bacteria are everywhere. Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. One example of bacteria is E .coli is a bacterium that is commonly found in the gut endotherms. E. coli and related bacteria constitute about 0.1% of gut flora‚ and fecal-oral transmission is the major route through

Reference: http://faculty.ccc.edu/tr-infectioncontrol/chain.htm In this essay I am going to be describing and explaining n about how pathogenic organisms grow and spread‚ by explaining each stage of the chain of infection‚ step by step and what they involve. This representive is used to help us understand the infection progression. A circle of linked components represent what happens in the cycle of infection

Any species of bacteria can turn into a superbug. A superbug is a strain of bacteria that is resistant to antibiotics. According to webmd.com "Every year‚ about 2 million people get sick from a superbug‚ according to the CDC. About 23‚000 die. Earlier this year‚ an outbreak of CRE (carbapenem-resistant enterobacteriaceae) linked to contaminated medical tools sickened 11 people at two Los-Angeles area hospitals. Two people died‚ and more than 200 others may have been exposed." This has become a serious

and antibiotics on bacteria. The hypothesis was that if bleach was used‚ it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro‚ erythromycin‚ and tetracycline for the antibiotics. All of these chemicals were used on the bacteria M. luteus. Two Petri dishes were covered in the bacteria and split into four

Introduction The working hypothesis being tested is if any of the three products; Scope Mouthwash (Scope)‚ LISTERINE® Antiseptic Mouthwash (Listerine)‚ Bactine Original First Aid Liquid (Bactine)‚ and Povidone-Iodine Solution‚ 10% Topical Microbicide Antiseptic (Iodine) are an appropriate antiseptic to can kill a sample bacterial contaminant found in the local environment‚ and if so‚ which is the most effective? The purpose of this experiment is to determine the antibacterial effectiveness of Scope

Abstract: It is important to be able to identify pathogenic bacteria that may be causing harm. Tomato crops can be affected by several different pathogenic bacteria. By using Koch’s postulates‚ it was determined that Pseudomonas syringae was the bacteria causing rot. There are four criteria that must be met when using Koch’s postulates. They are that the organism must be fund in all infected‚ the organism must be isolated in pure culture then once reinnoculated in a healthy host‚ must cause the

Viruses are made up of proteins and nucleic acids‚ they aren’t living whereas the others are. Viruses invade cells. They do not breathe or feed. Parasites are animals or plants that live off other animals or plants. 2. identify common illnesses and infections caused by bacteria‚ viruses‚ fungi and parasites Bacteria can cause food poisoning because of salmonella
